REMOVABLE HORSESHOE.

Specification of Letters Patent.

Patented Apr. 1%, 1921.

Application filed March 18, 1920. Serial No. 366,883.

To all whom it may concern Be it known that I, HARRY D. TOBIN, a citizen of the United States, residing at Empire, in the county of Leelanau, State of hlichigan, have invented certain new and useful Improvements in. Removable Horseshoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art. to which it appertains to make and use the same.

This invention relates to horseshoes, and has particular reference to shoes of the auxiliary tread-plate type.

The object of the invention is to provide a horseshoe of the above defined type in which the auxiliary tread-plate is secured to the hoof-carried member without the use of screws or similar fastening devices but, on the other hand, is secured by means pf 11 this construction, the auxiliary plate may be quickly removed or detached, and if the auxiliary plate l 15 sen left in position for a considerable period, it may be removed without the necessity of first removing rusted or battered bolts or nuts.

The advantages of auxiliary tread-plates are well known, and particularly in connection with my improved construction, it

is possible to have for quick attachment different tread-plates for use in icy and stormy weather.

lVith the above objects in view, and such others relating to the details of construction as may hereinafter appear, my invention will now be fully set forth and described, referencebeing had to the accompanying drawings.

In the drawings Figure 1 is a perspective View of the hoof carried section,

Fig. 2 is a perspective view of the auxiliarytread-plate.

Fig. 3 is a longitudinal section showing interengaging lugs and sockets, and

Fig. 4 is a longitudinal section showing the engagement of the lock plate with the base member or the hoof-carried element.

Referring more particularly to the drawings, 1 represents a base member or hoofcarried plate which is provided upon opposite sides with the usual nail holes 2. The hoof plate is 'shaped externally into the usual horseshoe contour, but between its arms'is spanned by a web plate 3 which extends from the toe of the plate 1 to a point practically half way to the heel. Substantially at the front end of the web 3, the plate is slotted on a line which extends transversely of the toe of the shoe by an inclined cut 4:, which provides a socket for the reception of a locking device as will hereinafter appear, Also the plate 1 is provided with a plurality 'of sockets 5 which are passed through the arms of the plate in substantially the same inclined direction as the cut 4, said sockets 5 being provided to receive a number of locking lugs carried by the auxiliary plate.

In Fig. 2 is disclosed the construction of the auxiliary plate 6, which is comparatively thin, as compared to the thickness of the plate 1, and conforms in general contour to the outline of the plate 1. However, the intermediate web 7 of the plate 6 does not extend as far to the rear as the web 3. The tread side of the plate 6 is provided with calks 8 which may be of any suitable form or assemblage, to suit the conditions of road or weather which govern at the particular period of use, and the hoof side of the plate is provided with a plurality of rearwardly inclined cam lugs 9 which correspond in form and inclination to the openin s or sockets 5 formed in the plate 1. F urt ermore, at the forward end of the web 7, the plate 6 is provided with a transverse pin 10 which extends through the pivotal end 11 of a lock plate 12 which is slightly curved longitudinally and is of spring material. The free end of the spring plate 12 is shaped into an upwardly opening hook 14, which coiiperates with a bar or rib 15 formed transversely across the plate 1 at the forward edge of the web 3.

In assembling the plate 6 and the plate 1, the free end of the spring plate 12 is first projected through the slot or cut 4. The plate 6 is then moved rearwardly relative to the plate 1 so that the plate 12 rides within the socket {1 of the web 3.-

As the rearward movement is continued the plates 1 and 6 are drawn more closely together,- until finally they stand in such a position that the points of the lugs 9 enter the sockets 5. Finally, the rib 15 engages the hook end of the plate 12, and as the lugs 9 finally scat snugly in the sockets 5, the end 14 snaps into locking engagement with the rib 15.

In separating the two parts, it is merely necessary to lift the free end of the plate 12 out of engagement with rib 15 by means of any suitable tool, and then to slide the plate 6 forwardly with relation to the plate 1 until the plates are separated in-the reverse order of theiriasseniblage.

From the foregoing, it will be apparent that I have provided a simple and efi'ective horseshoe of the auxiliary tread-plate type, in that the elements are assembled without the use of bolts or other fastening devices which may become rusted or mutilated so as to be practically {non-romovable. Furthermore the locking device is of such a character that it is well protected and safe from injurious contact with the road surface. i

hat I claim as my invention is:

1. A horseshoe. comprising in combination a base plate having a plurality o't sockets formed therein, an auxiliary plate shaped to the base plate and having lugs to interlock with said sockets, a lock plate hinged to the auxiliary plate. and a socket and tral'isverse rib on the base plate by which said lock plate is held to lock the auxiliary plate in position. p

2, A horseshoe, comprising in combination a base plate having a transverse slot near its. toe, a lock bar formed across the plate to the rear of the slot, an auxiliary plate, and a spring lock plate pivoted to the latter and adapted to be received first in said slot and then snapped on said lock bar.

3. Ahorseshoe, comprising in combination a base plate having a transverse slot near its toe, a lock bar termed across the plate to the rear of the slot, an auxiliary plate, and a spring lock plate pivoted to the lat ter and adapted to be received first in sai slot and then snapped on said lock bar, and intertitting sockets and lugs on the base plate and auxiliary plate respectively to relatively position the latter.

In testimony whereof, I afiix my signal ture in the presence'of two witnesses.
